Problems solved by technology

Cooling the mold through the cold water jacket set on the outer surface of the mold can have a certain effect on some common extrusion molds. However, for the production of radiator aluminum profile extrusion molds with too long teeth or complex shapes, due to The tooth height of the radiator produced by the mold is too long, the temperature on the outside of the mold working belt tooth-shaped cavity di

Abstract

The invention discloses a multistage-welding-chamber extrusion mould used for producing aluminium sections. The extrusion mould comprises an upper mould and a lower mould. The upper mould comprises a guide plate. The guide palate is provided with a plurality of flow distribution bridges. A plurality of flow distribution holes are formed among the plurality of the flow distribution bridges. The extrusion mould is characterized in that intersections of the flow distribution bridges are lower than a material feeding surface around to form recessed surfaces; slopes are disposed between the flow distribution bridges and the recessed surfaces on the material feeding surface for transition to form first pressure-relief angles; flow distribution hole and feeding openings in the recessed surfaces form second pressure-relief angles; two sides of the flow distribution bridges form third pressure-relief angles; the lower end of the guide plate is provided with multistage welding chambers communicated with the flow distribution holes; and the multistage welding chambers are disposed below the material feeding surface of the lower mould. The invention also discloses an extrusion technology for producing the aluminium sections by the extrusion mould. The multistage-welding-chamber extrusion mould can effectively control metal flow, and therefore the speed distribution in the section of the aluminium sections is uniform, the thickness of the mould is increased relatively, the mould intensity is enhanced, the stage of the welding chambers is increased, the welding pressure increases gradually, and the quality and the surface of the welding seams are improved.

Description

technical field [0001] The invention relates to the technical field of aluminum extrusion product manufacturing, in particular to a multi-stage welding chamber extrusion die for producing aluminum profiles and a production process. Background technique [0002] Aluminum products have a series of excellent properties, such as good strength, good weather resistance, and low density, and are often used to make radiator parts or exterior decorations. At present, in the production process of aluminum profiles, it is necessary to use extrusion dies to shape the aluminum profiles. When in use, the heat dissipation of the shaping die of the extrusion die is slow, and the heat dissipation effect is poor. Long-term use is easy to cause damage to the mold. [0003] In actual production, the extrusion die directly completes the plastic deformation of the metal, and is subjected to high temperature, high pressure, and high friction during the entire extrusion process, so it is easy to be...
